Okay, you could be on to something here Kamster.

If you think back to some of the Season 1 clues and Benry's behavior early, it does seem like everyone on the island before the Losties is "waiting" for something. Maybe Flight 815 was lost out of time somehow like that plane in Stephen King's Langoliers. Maybe it got sucked from 2004 to the Future. Maybe that's how Benry and the others "know" so much about the losties, they're in the future, and know the flight was deemed lost back in 2004, so all they did was some research on the casualty names from the flight list and pulled up some vital statistics.
Benry seems to be afraid of "He" whoever that is, and Desmond asked Locke "Are you Him?"....So maybe someone else from the past is coming - or could already be there...
The Nov. 29 date that Benry claimed muddies it up a bit, but we can work on that...

Ya keep throwing darts, one of them's bound to stick?
